On the bridge B, which is fastened to the bottom plate, C, are two clicks, Z) I), whose points pass through the plate C and engage between the teeth of the ratchet-wheel.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- The watch-barrel A, having its lower face provided with the ratch et-wheel a, as described, combined with the bottom plate, C, bridge B, and clicks 1) I), the latter passing through. the bottom plate, C, and engaging with said ratchet-wheel a, as and for the purposes described.
